Cable capacities
• All calculations allow for a 45% space
factor.
As there can be differences between data
cable sizes, Marshall-Tufflex recommend that
cable dimensions are confirmed with the
manufacturing company.
Fixing to Conduit and Mini Trunking
Elegance 170 can be used in conjunction
with Conduit and Mini trunking systems as
detailed in the diagrams below:
Elegance Aluminium
Accessory boxes
• Remove appropriate knockout and clip
box into trunking base.
• For boxes in same compartment as
supply, remove appropriate knockout and
clip box into trunking base.
• When boxes are installed consecutively, a
14mm wide length of cover is required to
cover the space between the boxes.
• Part M box assemblies with contrasting
coloured faceplates are available to meet
the requirements of DDA regulations for
Visual Impairment.
Covers
Covers are designed to limit unauthorised
removal and to remain in position during
normal conditions irrespective of impact
and minor undulations of the mounting
surface.
Covers – fitting
Covers are clipped into place from front.
If accessory boxes are installed, the LTL1/
LP1010 cover is butt-joined to the edge of
the box (ESSB1/2 only). Cut edges of the
cover are concealed by the accessory.
Covers – removal
To remove a cover, first detach an accessory
to gain access. The main cover can then be
gently eased off the base.
Screening
Aluminium containment will protect
all internal circuits from external
electromagnetic interference. For internal
segregation metallic dividing fillets are
available.
Offset dimensions
The minimum set that can be
accommodated in the same plane (from
internal to external bend), is 145mm.
Material
Aluminium trunking is manufactured from
high precision extruded aluminium with a
powder coat finish.
White RAL 9016
Silver Grey RAL 9006
Accessory boxes are supplied in PVC-U or
polycarbonate both of which are 100%
recyclable.
Installation
Positioning
Elegance can be installed at dado level or as
a bench-mounted installation.
Fitting
• Secure trunking base every 750mm.
• Secure using No.8 round head
screws and washers using the grooves
in the outer (110) or inner (170)
compartments of the base to facilitate
drilling Ø6mm holes.
• Avoid over-tightening to permit thermal
movement.
• The use of plastic caps over screw heads is
recommended to protect installed cables.
• To cut the trunking, use a fine tooth blade
(32/36tpi) or, preferably, a circular saw with
a 350mm diameter fine tungsten blade
(90/108tpi). This will produce an edge
requiring minimal de-burring.
• Consecutive lengths of base are aligned
and butt jointed together.
Earthing
• Base, covers and metallic fittings to be
cleaned of protective powder coatings for
earth bonding.
• Elegance 110: Incoming earth connection
is made using LBT1 bonding assembly
installed in the earth channel of the base.
• Elegance 170: Incoming earth connection
is made using LBT3 bonding kit, with edge
clip attached to the earth rib in the base and
faston connector crimped to incoming earth
cable.
• Bonding base to base: in final ring or radial
32Amp circuits, bonding strap LBS1 can
be used.
• Bonding end caps to base: use bonding
strap LBS5.
• Bonding base to cover, use LBS2.
Joints and bends
• Straight lengths should be butt jointed
together with the aid of LDP1 coupler pin
if required.
• Internal bends, external bends, flat angles
and tees are prefabricated in aluminium
and butt jointed together so cutting of
base and covers has to be very accurate to
produce a good finish.
